The invention also relates to all the stereoisomers and mixtures thereof of the compounds of the formulae (I) and (Ia), such as the E- and Z-isomers in the case of unsaturated structures or the optical isomers if chirality centers occur.

Possible salts of the compounds of the formulae I and Ia are, in particular, the alkali metal, alkaline earth metal or ammonium salts or ammonium salts which are substituted by one to four organic radicals (such as alkyl or hydroxyalkyl).

In the case where R⁴ and/or Y¹ =OH in particular, the salts are formed by deprotonation of the oxygen with the corresponding bases.

Bases which are preferably used for the salt formation are the hydroxides, alcoholates, hydrides or metal alkyls or aryls of the alkali or alkaline earth metals, such as, for example, sodium hydroxide or potassium hydroxide, sodium methylate or ethylate or potassium tert.-butylate, sodium hydride, potassium hydride or calcium hydride, methyl-, n-butyl-, tert.-butyl- or phenyllithium or ammonia or primary, secondary or tertiary amines, such as methylamine, diethylamine or triethylamine. The actual reaction is carried out by methods which are known to the expert.

The present invention also relates to processes for the preparation of the compounds (I) and (Ia), which comprise

a) reacting a compound of the formula (II) or (III) ##STR3## in which R¹, R², V, X, Y¹ and Y² have the same meaning as in the formulae (I) and (Ia), with a compound of the formula (IV) ##STR4## in which A, L, M, D, E, Q, G, W, Z, R⁴, R⁵, R⁶, n and m have the same meaning as in formulae (I) and (Ia), or

b) reacting a compound of the formula (V) or (VI) ##STR5## in which R¹, R², V, X, Y¹, Y² and Z have the same meaning as in the formulae (I) and (Ia) and X¹ represents a nucleofugic leaving group, such as, for example, halogen, (C₁ -C₆)-alkoxy, (C₁ -C₆)-alkylthio, phenyl, imidazolyl or triazolyl, with a compound of the formula (VII) ##STR6## in which A, L, M, D, E, Q, G, W, R³, R⁴, R⁵, R⁶, n and m have the same meaning as in formulae (I) and (Ia).

The preparation of the pyrimidine derivatives of the formulae (II) and (III) (for example Y=Hal, NH₂ or OH, Beilstein E III/IV, Volume 25, pages 4108-4109 or Beilstein II, Volume 24, page 270) and of the pyrimidine-5-carboxylic acid derivatives (V) and (VI) (for example Y=OH, NH₂, OEt ester or OPh ester) are known from the literature (K. Bredereck, R. Richter, Chem. Ber. 98, 131 (1965) or J.-L. Bernier et al., Bull. Soc. Chim. France 1976, 616).

The compounds of the formula (IV) are obtained by methods which are known from the literature from the amines of the formula (VII) (Houben Weyl E4, page 738 and page 834).

The amines of the formula (VII) can be prepared by processes which are known from the literature, such as, for example, by reaction of the corresponding aminophenols with fluorinated olefins (for example U.S. Pat. No. 3,409,274) or by reduction of the corresponding nitro compounds (for example J. Soc. Dyers Col. 42, 78 (1926)).

The reactions for the preparation the compounds I and Ia are carried out in the presence of a solvent which is inert towards the participants of the reaction. Preferred possible solvents are aliphatic and aromatic hydrocarbons, such as cyclohexane, toluene or xylene, ethers, such as dioxane, glycol dimethyl ether or tetrahydrofuran, chlorinated hydrocarbons, such as methylene chloride, chloroform or carbon tetrachloride, nitriles, such as acetonitrile, or mixtures of such solvents.

The reactions for the preparation of the compounds I or Ia are carried out at temperatures between -10° C. and the boiling point of the particular solvent used and over reaction times of 10 minutes to 12 hours. If Y¹ =hydroxyl, temperatures of 50° C.-120° C. and reaction times of 1-4 hours are preferred, and if Y¹ =amino or (C₁ -C₄)-alkylamino, 80°-180° C. and 2-10 hours are preferred. The reactions for salt formation are preferably carried out at -10-+70° C. over reaction times of 10 minutes-5 hours.

The compounds of the formulae IV and VII are novel and the present invention likewise relates to these compounds.

The active compounds have good plant tolerance and favorable toxicity towards warm-blooded animals and are suitable for combating animal pests, in particular insects, arachnida, helminths and mollusks, and especially preferably for combating insects and arachnida, encountered in agriculture, in animal breeding, in forestry, in the preservation of stored products and materials and in the hygiene sector.

The present invention thus also relates to veterinary pharmaceuticals which contain or consist of an effective amount of a compound of the formulae I or Ia.

The invention also relates to agents which contain the compounds of the formula I, in addition to suitable formulation auxiliaries.

The agents according to the invention in general contain the active compounds of the formula I or Ia to the extent of 1 to 95% by weight.

They can be formulated in various ways, depending on the biological and/or chemico-physical parameters. Appropriate formulation possibilities are therefore: wettable powders (WP), emulsifiable concentrates (EC), aqueous solutions (SC), emulsions, sprayable solutions, oil- or water-based dispersions (SC), suspoemulsions (SC), dusting agents (DP), dressings, granules in the form of microgranules, sprayed granules, coated granules and adsorption granules, water-dispersible granules (WG), ULV formulations, microcapsules, waxes or baits.

These individual types of formulation are known in principle and are described, for example, in: Winnacker-Kuchler, "Chemische Technologie (Chemical Technology)", Volume 7, C. Hauser Verlag Munich, 4th edition 1986; van Falkenberg, "Pesticides Formulations", Marcel Dekker N.Y., 2nd edition 1972-73; and K. Martens, "Spray Drying Handbook", 3rd edition 1979, G. Goodwin Ltd. London.

The formulation auxiliaries required, such as inert materials, surfactants, solvents and other additives, are likewise known and are described, for example, in: Watkins, "Handbook of Insecticide Dust Diluents and Carriers", 2nd edition, Darland Books, Caldwell N.J.; H. v. Olphen, "Introduction to Clay Colloid Chemistry", 2nd edition, J. Wiley & Sons, N.Y.; Marschen, "Solvents Guide", 2nd edition, Interscience, N.Y. 1950; McCutcheon's, "Detergents and Emulsifiers Annual", MC Publ. Corp., Ridgewood, N.J.; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., N.Y. 1964; Schonfeldt, "Grenzflachenaktive Athylenoxidaddukte (Surface-active Ethylene Oxide Adducts)", Wiss. Verlagsgesell., Stuttgart 1976; Winnacker-Kuchler, "Chemische Technologie (Chemical Technology)", Volume 7, C. Hauser Verlag Munich, 4th edition 1986.

Combinations with other pesticidally active substances, fertilizers and/or growth regulators can be prepared on the basis of these formulations, for example in the form of a finished formulation or as a tank mix. Wettable powders are preparations which are uniformly dispersible in water and which also contain, alongside the active compound, and in addition to a diluent or inert substance, wetting agents, for example polyoxyethylated alkylphenols, polyoxyethylated fatty alcohols and alkyl- or alkylphenol-sulfonates, and dispersing agents, for example sodium ligninsulfonate, sodium 2,2'-dinaphthylmethane-6,6'-disulfonate, sodium dibutylnaphthalenesulfonate or sodium oleyl-methyl-taurate. Emulsifiable concentrates are prepared by dissolving the active compound in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or higher-boiling aromatics or hydrocarbons, with addition of one or more emulsifiers. Examples of emulsifiers which can be used are: calcium alkylarylsulfonates, such as Ca dodecylbenzenesulfonate, or nonionic emulsifiers, such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxideethylene oxide condensation products, alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or polyoxyethylene sorbitol esters.

Dusting agents are obtained by grinding the active compound with finely divided solid substances, for example talc or naturally occurring clays, such as kaolin, bentonite, pyrophillite or diatomaceous earth. Granules can be prepared either by atomizing the active compound onto an absorbent granular inert material or by applying active compound concentrates to the surface of carriers, such as sand or kaolinites, or of granular inert material by means of adhesives, for example polyvinyl alcohol, sodium polyacrylate or mineral oils.

Suitable active compounds can also be granulated in the manner customary for the preparation of fertilizer granules--if desired as a mixture with fertilizers.

The active compound concentration in wettable powders is, for example, about 10 to 90% by weight, the remainder to make up 100% by weight consisting of the customary formulation constituents. The active compound concentration in emulsifiable concentrates can be about 5 to 80% by weight. Dust-like formulations usually contain 5 to 20% by weight of active compound, and sprayable solutions usually contain about 2 to 20% by weight. In granules, the active compound content depends partly on whether the active compound is in liquid or solid form and on what granulation auxiliaries, fillers and the like are used.

In addition, the active compound formulations mentioned contain, if appropriate, the particular customary adhesives, wetting agents, dispersing agents, emulsifiers, penetration agents, solvents, fillers or carriers.

For use, the concentrates in the commercially available form are diluted, if appropriate, in the customary manner, for example by means of water in the case of wettable powders, emulsifiable concentrates, dispersions and sometimes also microgranules. Dust-like and granular formulations and sprayable solutions are usually not additionally diluted with further inert substances before use.

The application amount required varies according to the external conditions, such as temperature, humidity and the like. It can vary within wide limits, for example between 0.005 and 10.0 kg/ha or more of active substance, but is preferably between 0.01 and 5 kg/ha.

The active compounds according to the invention can be present in their commercially available formulations and in the use forms prepared from these formulations as mixtures with other active compounds, such as insecticides, attractants, sterilizing agents, acaricides, nematicides, fungicides, growth-regulating substances or herbicides.

The active compound content of the use forms prepared from the commercially available formulations can be from 0.00000001 to 100% by weight of active compound, preferably between 0.00001 and 1% by weight.

They are used in a customary manner appropriate for the use forms.

The active compounds according to the invention are also particularly suitable for combating endo- and ectoparasites in the veterinary medicine sector and in the field of animal husbandry.

The active compounds according to the invention are used here in a known manner, such as by oral application in the form of, for example, tablets, capsules, drinks or granules, by dermal application in the form of, for example, dipping, spraying, pouring on and spotting on and dusting on, and by parenteral administration in the form of, for example, injection.

In a pour-on formulation, the active compound is dissolved, emulsified or suspended in a suitable solvent or solvent mixture which is tolerated by the skin, if appropriate with the addition of further auxiliaries, and the solution, emulsion or suspension is applied to the skin of the animal to be treated with the aid of a suitable device (for example with the aid of a measuring beaker, a spray bottle or a metered syringe).

Pour-on formulations of insecticides and anthelmintics have already been disclosed in veterinary medicine (in this context, see Rogoff, W. M. and Kohler, P. H., J. Econ. Ent. 53, 814-817 (1960) and EP-A 45,242). The term "pour-on formulation" or "spot-on formulation" is familiar to the expert. Such a formulation is a liquid preparation which is suitable for so-called "pour-on application" and is poured onto the skin (pour-on treatment).

The novel compounds of the formula I according to the invention can accordingly also be particularly advantageously employed in animal husbandry (for example cattle, sheep, pigs and poultry, such as chickens, geese and the like). In a preferred embodiment of the invention, the novel compounds are administered orally to the animals, if appropriate in suitable formulations (see above) and if appropriate with the drinking water or feed. Since the excretion in the feces is effective, the development of insects in the feces of the animals can in this way be very easily prevented. The particular suitable dosages and formulations depend, in particular, on the species and development stage of the stock animals and also on the pressure of infestation, and can easily be determined and specified by the customary methods. The novel compounds can be used on cattle or sheep, for example, in dosages of 0.01 mg to 1 g/kg of body weight.

The following examples serve to illustrate the invention.

A. FORMULATION EXAMPLES

a) A dusting agent is obtained by mixing 10 parts by weight of active compound and 90 parts by weight of talc, as the inert substance, and comminuting the mixture in an impact mill.

b) A wettable powder which is readily dispersible in water is obtained by mixing 25 parts by weight of active compound, 65 parts by weight of kaolin-containing quartz, as the inert substance, 10 parts by weight of potassium ligninsulfonate and 1 part by weight of sodium oleyl-methyl-taurate, as the wetting and dispersing agents, and grinding the mixture in a pinned disk mill.

c) A dispersion concentrate which is readily dispersible in water is prepared by mixing 40 parts by weight of active compound with 7 parts by weight of sulfosuccinic acid half-ester, 2 parts by weight of a sodium ligninsulfonate and 51 parts by weight of water and grinding the mixture to a fineness of less than 5 microns in a bead mill.

d) An emulsifiable concentrate can be prepared from 15 parts by weight of active compound, 75 parts by weight of cyclohexanone, as the solvent, and 10 parts by weight of oxyethylated nonylphenol (10 mol of ethylene oxide), as the emulsifier.

e) Granules can be prepared from 2 to 15 parts by weight of active compound and an inert granule carrier, such as attapulgite, pumice granules and/or quartz sand. A suspension of the wettable powder from Example b having a solids content of 30% is advantageously used, this is sprayed onto the surface of attapulgite granules and the components are dried and intimately mixed. The weight content of the wettable powder here is about 5% and that of the inert carrier about 95% of the finished granules.

C. BIOLOGICAL EXAMPLES: EXAMPLE 1 Lucilia test

The substances are dissolved in a mixture consisting of dimethylformamide (85 g), ®Emulsogen (7 g) and ®Arkopal N 60 (3 g) so that dilution series containing active compound concentrations of 10,000/1,000 ppm are obtained. 1 ml portions of these solutions are intimately mixed with 9 g of finely ground meat, so that in the end meat having active compound concentrations of 1,000/100 ppm is available. As a control, 1 ml of solvent is added to 9 g of meat.

20 freshly emerged larvae of Lucilia cuprina are in each case added to the larval nutrient media thus prepared. After 72 hours, when the larvae I have developed to the pupation-ready larvae III in the control medium, the mortality rate is determined. In this test, the compounds according to Examples 3, 4, 6, 10, 12, 28 and 29 (Table 3) brought about 100% destruction of the larvae at an active compound concentration of 100 ppm.

EXAMPLE 2 Nematode test; in vitro

In the in vitro experiments, nematodes are kept in a culture medium to which the test substance is added for up to 5 days. The motility of the nematodes and their reproduction on the 6th day of the experiment is investigated and measured in comparison with untreated control cultures.

EXAMPLE 3 Nematode test; in vivo

In nematode experiments, laboratory rodents, dogs (±10 kg body weight) or lambs (±20 kg body weight) are infected with their natural or adapted nematodes, and when the prepatency period has elapsed the egg excretion is checked coproscopically several times until it has stabilized. The animals are then treated with the test substance, once or several times, by various administration routes and at various dosages. A maximum of 400 mg/kg of body weight is administered to laboratory rodents and 50 mg/kg of body weight to large animals. The result of treatment is checked coproscopically up to four weeks after the administration, and if the egg excretion has been reduced by more than 90%, a helminthological section is performed and the worm loads are compared with those of an untreated control group.

EXAMPLE 4 Nematode test

Lambs weighing ±20 kg of body weight are infected orally with metacercaria of the trematode Fasciola hepatica. When the prepatency period has elapsed, the level of excretion of Fasciola eggs is repeatedly checked coproscopically; when the egg excretion has stabilized, medicamentous treatment is performed by an administration route which changes from case to case. The dosage is likewise variable, is administered once or several times and is a maximum of 50 mg/kg of body weight. The success is checked coproscopically up to four weeks after administration, and in the case of an egg reduction of more than 90% a helminthological section is performed. The evaluation is performed as a "controlled test", that is to say in comparison with an untreated experimental group.
